To @ZZ whom t may concern,.-

Be it known that I, GERRITT J. LIEZEN, of Hingham, in the county ofSheboygan and State of Wisconsin, have invented a new and usefulImprovement in Cheese-Vats, of which the following is a description,reference being had to the accompanying drawings, which are a part ofthis specification.

In the separation and conversion of milk into cheese and theresiduumwhey it is desirable to raise the temperature of the milk to such heightas to cause the separation and conversion to be accomplishedcomparatively quickly. For this purpose a vat with apparatus adapted forapplying heat to the milk is employed.

My invention relates to improved apparatus or devices for heating themilk in connection with the vat and to improvements incidental tothebest and most satisfactory use of the vat and the heating devices.

The invention consists of the devices and combinations of deviceshereinafter described Fig.v5,is a longitudinal section of a feature ofthe heating apparatus on line 5 5 of Fig. 3.

. Figs. 6 and 7 are transverse sections on lines 6 6 and 77,respectively, of Fig. 5. Fig. 8 is a section on line 8 8 of Fig. 3 ofthe vat-faucet and its attachments. Fig. 9 is a plan, partly ,insection, of a modified form ofthe apparatus. Fig. 10 is a frontelevation of the tank, a part being broken away, of the form shown inFig. 9. Fig. 11 is ay section showing a slightly-modified form ofthe'vat or wheyfaucet. Fig. 12 is a plan, with parts in section, ofanother modified form of the construction. Fig. 13 is a front elevation,parts being broken away, of the form of construction shown'in FigI l2. yFig. 14 is a detail of the heating apparatus. Fig. 15 exhibits amodified form of whey-faucet in connection with a stationary vat andtank.

In the drawings, A is a tank supported on suitable legs. The vatl B,also preferably constructed of sheet metal, is somewhat smaller in sizethan the tank A and is preferably provided with a flange C around itsedge at the top, which flange normally rests on the top of the tank,permitting the vat to depend therefrom into the tank. When used, Wateris put into the tank and the vat is lifted thereby and floats therein.The milk to be' heated and separated and converted into cheese and Wheyis put into the vat B.

For heating the water in the tank A the tank is provided with a numberof longitudinally-disposed flues D D, fixed permanently in and throughthe lower portion of the tank A. At the rear end these iues D D are openinto alsmokei-chamber E, providedwith a smoke-discharging orifice F.

This apparatus may be used with wood or other material for producingcombustion, but

I prefer to employ therewith gas or vapor, ad.

visably such as is readily produced or generated from a volatilekerosene-oil or gasolene.

For this purpose I have provided special devices adapted to supplykerosene-oil to convert it into vapor or gas and to accomplish its rapidand satisfactory combustion in the iiues D D. A pipe 1, leading from areservoir to the burners, is adapted by gravity to supply kerosene-oilor gasolene thereto. A shutoff cock 2 is provided to limit and controlthe supply of the liquid. The pipe y1 leads to the vaporizing device 3,located in this instance in the central flue D, which vaporizin g devicedischarges through a cone 4 into a burner in the same central iiue, andalso discharges into branch pipes 5 5, leading to cones 4' 4', thatdischarge into burners in the other flues. The cones 4 4 are providedwith needlevalves 6 6, that close the discharge-orifice through thesecones, and by which valves the supply of rrvapor or gas may be limitedor stopped. A needle valve 7 also closes the port leading from thevaporizing device 3 into the branch pipes 5. The needle-valves areprovided with stems having screw-threads thereon that turn incorresponding threads ICO in the body of the cones, whereby the valvesmay be opened and closed. The cones 4 4' discharge, respectively, intoelongated perforated tubular burners 8 8, preferably of truncated-coneform and closed at their rear ends. In the instance of the cone 4 itdischarges into the burner 8 through an interposed sleeve 0, thatextends from the cone through the rear portion of the vaporizin g device3 to the burner 8. In the vaporizing device there is a short horizontaltube 10, leading from the pipe 1 to an annular Vaporizing, chamber l1,and therefrom a tube 12, extending horizontally above the tube 10, leadsto the cone 4 and to the branch pipes 5. The cone 4 is located betweenthe tubes 10 and 12, and the sleeve 9 is located mostly between the sametubes 10 and 12 and leads from near the cone 4 through the center of theannular chamber 11 and discharges into the burner 8. An annular enlargedchamber 13, which is continuous with the passage through the sleeve 9,is provided with radially-disposed burner-openings 14, through whichvapor is discharged and at which it burns in the fiue D, as will beunderstood by reference to Figs. 5 and 4. A rod 15 is slidable endwisein bearings therefor in the frame of the vaporizing device and carrieson its extremity a cover or plug-valve 16, adapted to fit over the endof the sleeve Sand practically close it. A pan 17, Fig. G, suspendedunder the tube 10 and chamber 11, is adaptedto hold a small supply ofga-solene for combustion when commencing to use the device to convertthe gasolene in the tube 10 and chamber 11 into vapor or gas. It must beunderstood that the vaporizing device 3 and the several cones 4 4 and'the burners S are located in the front endslof the several flues D andthat there is such space around these burners in the several fines as topermit of air passing freely through the filles from front to rear. Inusing these devices a small supply of gasolene is placed ln the pan 17,and a supply of gasolene is permitted to flow into the tube 10 andthrough itinto the lower portion of the chamber 11. The gasolene in thepan 17 is then lighted and heats the tube 10 and its contents and thecontents of chamber 1l to such extent as to vaporize it, the vaporflowing through the tube 12 to the cone 4, which is then opened, and thegas or vapor discharged therefrom is lighted and burns in the sleeve 9,and out through the apertures 14 of the chamber 13, the valve 1t closingthe end of the sleeve 9, whereby the vaporization is made more extensiveand complete, supplying a sufficient quantity to be delivered to anddischarged from the cones 4 4 through the pipes 5, the valve 7 havingbeen opened therefor. As soon as the combustion has produced sufficientheat in the vaporizing device to thoroughly vaporize the supply ofgasolene being delivered thereto the -valve 16 is pushed away from thesleeve 9, permitting the vapor and combustion from the conc 4to mostlypass through the sleeve 9 into thc burner 8, where the combustion isintensified and completed.

Vhen the milk contained in the vat Blhas been separated and convertedinto cnrd and whey, it is desirable to be able to draw off a portion orall of the Whey, either immediately or from time to time, and for thispurpose a properly-constructed faucetis desirable. As the vat fioats onthe water in the tank A it is liable to rise and fall therein to acertain cxtent, and to accommodate this rising and falling of the vatand to provide a satisfactory faucet for use in this place I haveprovided a hollow boss or short tube 1S, which is inserted at one end inan aperture therefor in the lower part of the end of the vat, the bossor tube being provided with flanges that fit against the end and bottomof the vat, and the tube 19, having a downwardly-discharging orifice, issecured to the hollow boss 1S and is made continuous therewith. Aninwardly-closing valve 20, adapted to close the inner end of the tube18, is provided with a screw-threaded stem that turns through the outerend of the tube 19, whereby the valve is adapted to be opened andclosed. This tube 19 passes through the end of the tank A in avertically-elongatcd slot therefor, and disks or plates 21, one on theinside and the other on the outside of the end wall of the tank, arefitted thereto over the slot-aperture and slide vertically on the wallin ways therefor secured to or integral with the end wall of the tank.The slides 2l 21 encompass and are secured to the tube 1f), making awatertight joint thereabout and also on the end wall of the tank. Theouter end of the tube or boss 1S fits against the inner slide 21, and anut 22, turning by screw-thread on the tube 19,bears against the ou tersurface of the other plate 21, thus holding them in position, but sothat they can slide freely, though watertight, vertically, on the endplate of the tank. This construction permits of the sufficient rise andfall of the vat B to accommodate its rise and fall in the water of thetank. The tlues D D are conveniently secured in the tank A by means ofnuts G G, turning on theends of the flues against the inside andoutside, respectively, of the end walls of the tank. A cock 23 isprovided for discharging the water from the tank.

In Figs. 9 and 10 there is shown a modified form of the heating devices.In this form of construction there is a combustion-chamber H, located inthe front end of the tank initial to and continuous into the flues D D.The vaporizin g devices and burners are located in this initialcombustion-chamber instead of being directly in a combustion-flue, as inthe preferable and foregoingdescribed form of construction. In this formof device the supply-pipe 1 runs into the combustion-chamber and iscoiled about one or more of the combustion sleeves or burners, forming avapo- IOC IIO

be capable of being removed from the com-v rizing device 3', andtherefrom leads to the` front of and so as to discharge toward and intothe iues D' D. The cone 24' discharges through a short pipe into thetransverselydisposed perforated tube-burner which is also located in thecombustion-chamber, and is preferably constructed in sections, so as tobustion-chamber Withthe other burners and Vaporizing device, if desired.It will be understood that the vapor discharged into and burning fromthe burner 25' is adapted directly to heat the combustion-chamber`H andalso to vaporize the liquid in the vaporizing device 3', while the vaporthatis discharged through the cones 24 goes mostly into the burners 25,which are adapted for delivering the `heat and products of combustionalmost directly into the ilues D', thus making of these iiues bothcombustionv and heating spaces, substantially like the flues in the rstform of device described. .In thisform of apparatus the burners andvaporizing device that are located inthe combustion-chamber are soconstructed and supported in the chamber as to be capable of beingremoved therefrom without much difficulty, and when so removed thecombustionchamber may be Y utilized for building a ire therein with woodor other combustible material. It will be noted that there aredoor-openin gs 26 through the front end of the tank into thecombustionchamber, and theseare provided for removing the burners andvaporizing device shown in the drawings and are adapted for admittingwood or other material to the combustionchamber when this is used forheating purposes. I have provided ears 27 on the tank adjacent to thedoor-openings for hanging and securing doors thereon for closing thecombustion-chamber when Wood orother inlflammable material isinsertedand burned the front end of the tank about the elongatedvertical slot therein, and these plates are provided with ways in whichthe slides21 are adapted to move vertically water-tight. This form ofconstruction permits of connecting the faucet movably with the end ofthe tank when such end wall is constructed without ways for the slides2l directly thereon. In this form of device I also show a valve 20',having its seat on the inside of the tube or valve-throat 18',the valvethus being arranged to close against the flow of the liquid.

In Figs. 1,2, 13, and 14 I show still another modified forni of heatingapparatus, in which there arefour flucs D2 D2, the two inner ones beingutilized for the passage of heat and the products of combustion towardthe rear of the tank, and the other two are utilized for the passage ofthe heat and products of combustion on their return toward the front ofthe apparatus. In this form of device the smoke-chamber E' is located atthe front, and connecting fiues or chambers I I are provided at the rearthat connect the flues D2 D2 in sets, providing for the outward andreturn flow of the heat and products of combustion therethrough. supplypipe 12 leads by its branches directly into the combustion flues orchambers D2 and is there coiled, forming a vaporizing device 32, andthence it leads back to the cones 42, so disposed as to dischargedirectly into the flues D2. In this form of device the whey=dis chargingfaucet is preferably located at the rear end of the tank.

In Fig. 15 I have shown a form of wheydischarging faucet involving mypeculiar construction except in the absence of the means for permittingof vertical movement of the faucet in the wall of the tank, thisparticular form of faucet being adapted for use with a vat and tankwhere the vat is stationary in the tank.

What I claim as my invention is- 1.
